GRAIN-ELEVATOR.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed December 4,1916. Serial No. 135,018.

T 0 all whom it may concern Be it known that we. ROBERT HENRY HAY- wannand CHARLES lVAnn BROWN, both of the city of Winnipeg, in the Provinceof Manitoba, Canada, have invented certain new and useful Improvementsin Grrain Elevators, of which the following is the specification.

The invention relates to an improvement in grain elevators and theobject of the invention is to provide a device for elevating grain in aneasy, quick and efficient manner, and it consists essentially in thearrangement and construction of parts hereinafter more particularlydescribed and later pointed out in the appended claim, reference beinghad to the accompanying drawing in which Figure 1 represents a side viewof the elevator.

Fig. 2 is a vertical sectional view through the elevator.

Fig. 3 is a plan view with part of the easing removed to expose interiorparts.

Fig. 4 represents a perspective view of one of the wings.

In the drawing like characters of reference indicate corresponding partsin each figure.

1 and 2 represent side sills on which we mount a pair of standards 3 and4f, the standards being fitted with suitable bearings which receiverotatablv a cross shaft 5. This shaft is fitted with a chain wheel 6 bymeans of which it can be driven such as by an endless chain indicated at7.

The side sills are connected by cross sup ports 8 and 9 and thesesupports, together with the sills, carry a cylindrical casing 10 mountedconcentric to the shaft 5.

An outlet chute 11 is formed as part of the casing and it passesvertically tangentially to the casing at the top side.

12 is a delivery spout communicating with the chute.

One of the sides of the casing, indicated at 10, is supplied with an airinlet opening 13 arranged concentric to the shaft 5.

On the shaft, at the opposite side of the casing and within the same, wemount a disk 14 which has a diameter somewhat larger than the diameterof the opening 13, and to this disk \we attach, in the present instance,four similar wings 15, 16, 17 and 18 constructed as now described.

Each wing consists of a more or less ported in any suitable manner.

substantially rectangular plate 19 having spaced, parallel, lengthwiseextending ribs 20 on the the one face thereof. Each wing is secured tothe disk by means of an angle brace 21 permanently fastened to the backface of the wing and to the inner side of the disk. An inclined bracerod 22 is inserted also between the back side of the wing and (tihekendofthe angle brace attached to the All of the wings are fastened in theabove manner so that their inner ends are equal distance from the shaftand so that the plates 19 pass radially outwardly from the shaftand aregrouped in opposing pairs. Further, the inner ends of the wings arelocated such that in the turning of the disk, in the rotation of theshaft, the inner ends of said wings rotate in a circle having a diametersomewhat greater than the diameter of the air inlet opening. The outertips of the wings just nicely clear the inner wall of the casing.

23 is a feed spout for feeding grain into the'casing. This feed spoutcan be sup- The discharge end of the spout enters the interior of thecasing in a location between the circle containing the inner ends of thewings and the air inlet opening and in a position horizontally oppositethe shaft and to the left hand side thereof. Actually, the discharge endof the spout is set into the edge of the opening 13 by cutting away apart of the side 10 of the casing, as shown at 24 in Fig. 1 of thedrawing, the notch or out being made in a location horizontally oppositethe shaft 5 and to the left hand side.

From the above it is obvious that upon the shaft being driven the wingswill be rotated around the inner or discharge end of the feed pipe, theinner end of which discharges the grain to the center of the casing, asbest shown in Fig. 3 of the drawing, where it will be observed that theinner end of the spout terminates centrally between the opposing wallsof the casing.

This elevator is to be driven at a high rate of speed through the chain7 and in the direction indicated by the applied arrows Figs. 2 and 8.

As the grain indicated by the reference numeral 25 (see Fig. 2) fallsfrom the delivery end of the spout, it will be caught by the wings anddischarged. up the chute 11 e to the spout 12. As the machine is rotated'plain,if one refer to Fig. 2, it will be obvious that the grain ininitially dropping from the inner end of the pipe will be primarilycaught on the inner end of the then lowermost wing and before it escapesfrom that wing it will be slid bodily over the win from the inner end tothe outer end thereo O'wng to the high rate of speed at which the wingsare traveling the grain will accordingly be projected from the outer tipof the wing at a high velocity and in the actual machine the arrangementis such that at the instant the grain has reached the outer tip of thewing the said wing has reached the chute 11 so that the grain is thrownoff the wing upwardly into the chute. The combined effect of thisthrowing action of the grain from the wings together with the velocityof the air up the tor.

chute gives us a very eflicient grain elevabe obvious that if no suchribs were pro vided the grain could crowd to the sides and drop downbetween the sides of the casing and the edges of the wings. This would.be detrimental, as will'be readily appreciated. 7

What we claim as our invention is In a grain elevator the combinationwith a' cylindrical casing and a rotatably' mounted cross shaft passingcentrally through the casing, ofa disk permanently'secured to the shaftand located adjacent the inner side of one of the ends of thecasingan'cl a'plurality of radially disposed wings secured to the diskand operative -within the casing and having their front faces fittedwith longitudinally extending ribs, said ribs being located at the freeedges and at intermediate points of the wings as and for the purposespecified.

Signed at Winnipeg, this 22 day of November, 1916.
